After a summer stall, the dollar bull-run is back

The U.S. dollar looks set to shake off its summer lull as the factors for a renewed rise appear to be firmly in place.

Upbeat economic data, rising Treasury yields and Federal Reserve tapering expectations have boosted sentiment on the greenback, which hit a six-week high around 100.20 yen on Friday, and held close to a seven-week peak hit against the euro on Thursday following dovish comments from the European Central Bank.

A rise in 10-year Treasury yields to 3 percent on Thursday, their highest level since July 2011, following stronger-than-expected economic data has refocused attention on the U.S. currency.

"We had a temporary pause in July when bond yields pulled back and the dollar paused, but now we're near that 3 percent level and there's renewed focus on payrolls and the Fed meeting this month, so for sure we're going to see another bout of dollar strength," Nick Bennenbroek, head of currency strategy at Wells Fargo, told CNBC Asia's "Squawk Box" on Friday.

The euro hovered around $1.3124 on Friday, within sight of Thursday's seven-week low at $1.3109 and down about 2.4 percent from a six-month peak hit last month.

Among the upbeat economic data lending to positive dollar sentiment, Thursday's survey from the Institute for Supply Management showed services industries in August posted their fastest growth since December 2005, exceeding market expectations.

Meanwhile, news that weekly jobless claims declined to a near five-year low has lifted expectations for a stronger-than-expected non-farm payrolls report on Friday.

Strong jobs data could cement expectations that the Fed will start to unwind its monetary stimulus when it meets later in September – a backdrop that is seen as favorable to the U.S. dollar at a time when central bank stimulus measures are putting pressure on other major currencies.

"I think we are ready to see another round of the dollar being bid higher, especially with the non-farm payrolls report coming out," said George Dowd, head of Chicago foreign exchange at Newedge, a brokerage. "Initial reads [on the jobs market] we've had during the week point to a pretty strong number."

Economists polled by Reuters forecast 180,000 new jobs were created in August compared with 162,000 in July. They expect the unemployment rate to remain unchanged at 7.4 percent.
